Binding a mipmap as UAV to a compute shader causes validation errors with WebGPU

WebGPU

-

Steps to reproduce:

  1. Open attached project WebGPUMipBug.zip.
  2. Open SampleScene.unity.
  3. Make sure that Web platform is selected in the build window, and that the graphics library is set to WebGPU.
  4. Build and run.
  5. Open the browser console and observe validation errors.

Error message:

 
{code:java}
mipLevelCount (4) of [TextureView of Texture (unlabeled 8x8 px, TextureFormat::RGBA8Unorm)] expected to be 1.
 - While validating entries[0] against { binding: 0, visibility: ShaderStage::Compute, storageTexture: {format: TextureFormat::RGBA8Unorm, viewDimension: TextureViewDimension::e2D, access: StorageTextureAccess::WriteOnly} }.
 - While validating [BindGroupDescriptor] against [BindGroupLayout "TestCompute.CSMain_BindGroupLayout[0]_693"]
 - While calling [Device].CreateBindGroup([BindGroupDescriptor]). {code}
{code:java}
(index):1 [Invalid BindGroup "TestCompute.CSMain_BindGroup[4]_696"] is invalid.
 - While encoding [ComputePassEncoder (unlabeled)].SetBindGroup(0, [Invalid BindGroup "TestCompute.CSMain_BindGroup[4]_696"], 0, ...).
 - While finishing [CommandEncoder (unlabeled)]. {code}

Actual results: Validation errors, shader fails to execute.

 

Expected results: No validation errors, shader works.
